摘　　要：为了预测垃圾焚烧厂排放的废气量并了解废气污染情况的指标特征,文中设计和实现了垃圾焚烧厂废气排放的可视化分析系统。文中在分析废气扩散的主要影响因素的基础上建立了基于高斯点源扩散的垃圾焚烧厂废气的扩散模型,并基于该扩散模型设计并实现了废气浓度等值线图绘制方法。在百度地图上绘制全国垃圾焚烧厂的分布图、垃圾焚烧厂废气浓度扩散等值线图,并通过动态柱状图、时间轮与柱状图相结合的方法显示垃圾焚烧厂的实时排放情况,实现了垃圾焚烧厂排放数据的可视化。可视化系统将废气的各项指标数据进行图形化展示,达到了实时监控废气污染物的目的。In order to predict the amount of waste gas emitted from solid waste incineration plants and understand the characteristics of the indicators of the pollution of the exhaust gases,a visualization system for waste gas emitted from solid waste incineration plants was designed and implemented.Based on the analysis of the main factors affecting the diffusion of waste gas,the diffusion model of waste gas in solid waste incineration plant based on Gaussian point source diffusion was established,and the method of drawing the concentration contour map of waste gas was realized based on the diffusion model.The distribution map of the solid waste incineration plant in China and the contour map of the emission concentration of solid waste incineration plant were plotted on Baidu map.Through the combination of dynamic histogram,time wheel and histogram,the real time emission of solid waste incineration plant is displayed,and the visualization of exhaust emission data of solid waste incineration plant is realized.The visualization system displays the waste gas data graphically,so as to achieve real-time monitoring of exhaust pollutants.
